HLU classes - alphabetically

AnnoManager

The AnnoManager object allows an arbitrary user-created View object to be managed as an annotation of a plot object.

App

The App object is used to manage resource databases.

Base

The Base object provides the base functionality used by all objects in the HLU library.

ContourPlot

The ContourPlot object draws line or filled contours with labels and annotations.

CoordArrTable

The CoordArrTable object provides a way to describe X/Y coordinate data to the HLU library.

CoordArrays

The CoordArrays object provides a way to describe X/Y coordinate data to the HLU library.

DataComm

The DataComm object provides the functionality for its Subclasses to communicate with DataItem objects.

DataItem

The DataItem objects provide a way to describe data to the HLU library.

DataSpec

The DataSpec objects provide a way to describe data- specific plot attributes.

Error

The Error object provides configuration options for the error reporting module of the HLU library.

GraphicStyle

The GraphicStyle class provides grouped attributes for drawing primitives.

IrregularPlot

The IrregularPlot object draws immediate mode lines and may be used to map overlay plots into an irregular rectangular coordinate space.

IrregularTransformation

The IrregularTransformation object manages forward and reverse transformations in an irregular rectangular coordinate space.

LabelBar

The LabelBar object draws an annotation for fill styles with an optional title and/or border.

Legend

The Legend object draws an annotation for line and/or marker styles with an optional title and/or border.

LogLinPlot

The LogLinPlot object draws immediate mode lines and may be used to map overlay plots into a log or linear coordinate space.

LogLinTransformation

The LogLinTransformation object manages forward and reverse transformations in log or linear coordinate space.

MapPlot

The MapPlot object draws outlined and/or filled maps of arbitrary regions of the globe and may be used to map overlay plots into a number of standard projections.

MapTransformation

The MapTransformation object manages forward and reverse transformations in the coordinate space defined by various map projections.

NcgmWorkstation

The NcgmWorkstation manages communication with the NCAR Graphcs CGM Workstation output device.

Obj

The Obj class is a simplified version of the Base class.

PSWorkstation

The PSWorkstation object manages communication with the NCAR Graphics PS Workstation output device.

PlotManager

The PlotManager allows a plot object to manage overlays and annotations.

ScalarField

The ScalarField object supplies two dimensional scalar field data.

StreamlinePlot

The StreamlinePlot class represents a vector field by drawing streamlines.

Style

The Style class provides its subclasses with the ability to group attributes.

TextItem

The TextItem object draws arbitrary text.

TickMark

The TickMark object draws tickmarks along any of the sides of a plot.

Title

The Title object draws main, X and Y axis titles for a parent plot or overlay object.

Transformation

The Transformation classes manage forward and backward transformations for the Transform classes.

Transform

The Transform class provides its sub-classes with the ability to handle coordinate transformations.

VectorField

The VectorField class supplies two-dimensional vector field data.

VectorPlot

The VectorPlot class represents a vector field by drawing arrows at points of a grid.

View

The View class provides its sub-classes with an ability to be drawn.

Workspace

The Workspace object manages large blocks of memory on behalf a number of HLU library objects.

Workstation

A Workstation object manages an instance of an output device.

XWorkstation

The XWorkstation manages communication with the NCAR Graphcs X Workstation input/output device.

XyDataSpec

The XyDataSpec object is used to specify data-specific plot attributes to the XyPlot object.

XyPlot

The XyPlot object draws curves made up of X/Y coordinate pairs with tick marks, titles, and a legend.
